［摘要］徐州生物醫(yī)藥產(chǎn)業(yè)園5#孵化中心建筑總高度59-8m，兩棟塔樓采用框架-剪力墻結(jié)構(gòu)體系，在頂部由兩個連廊連接成整體。建筑地上12層，地下2層，屬于超限高層建筑。兩個高位連廊跨度33-6m，總寬度20-5m，高度9-15m，采用鋼桁架結(jié)構(gòu)，弦桿采用H型鋼，腹桿采用方鋼管，連廊與兩側(cè)塔樓之間采用剛性連接。采用抗震性能化設(shè)計方法，對主體結(jié)構(gòu)進行小震彈性計算、中震和大震性能驗算以及大震彈塑性時程分析，并重點對高位連廊鋼結(jié)構(gòu)進行了針對性分析。11層和屋面層連廊位置處樓面的樓板有效寬度變小，因此對樓板進行了專項受力性能分析。最后，根據(jù)結(jié)構(gòu)各階段性能分析結(jié)果對薄弱部位采取針對性加強措施，確保結(jié)構(gòu)在滿足建筑功能、經(jīng)濟合理的條件下具有較好的抗震性能。

Abstract:The height of the 5# incubation center in Xuzhou Bio-medicine Industrial Park is 59-8m, and the two tower are frame-shear wall structure, connected to be a unit by two corridors at the top of towers. The building has 12 stories above ground and 2 stories underground, and it is an overrun high-rise building. The two elevated corridors are both 33-6m long, 20-5m wide and 9-15m high, and adopt steel truss structure. The chord members of steel truss are H-shaped steel and the web members of steel truss are square steel tube. The corridors and the tower are rigidly connected. Using the performance-based seismic design method, the elastic analysis under small earthquake, the performance checking calculation under moderate earthquake and rare earthquake, and the elastic-plastic time-history analysis under rare earthquake were carried out for the main structure in detail. And the pertinence analysis of the steel structure of the elevated corridors was also conducted. The effective width of floor is reduced at the position of elevated corridors in 11th floor and roof floor. Thus the special mechanical behavior analysis of the floor was carried out. At last, according to the analysis results of each stage, measures were taken to strengthen the weak parts, to ensure that the structure has better seismic performance under the condition of satisfying the building function and reasonable economy.
Keywords:connected structure; performance-based seismic design; elastic-plastic time-history analysis; slab mechanical behavior analysis
